18/2 Fire Alarm Riser FPLR Solid Bare Copper Cable – 1000ft – Yellow

Choose 18/2 Fire Alarm Riser Cable for Compliance

The 18/2 fire alarm cable is a trusted option for life-safety systems requiring secure and low-voltage connections. It provides safe and consistent performance in vertical runs between floors with 18 AWG copper conductors and riser-rated jacketing.

Technical Overview: What Does it entail?

The 18/2 plenum fire alarm cable and riser version differ mainly in jacket composition. Riser-rated jackets meet NEC CMR standards, restricting flame spread in vertical shafts.

Shielded options like the 18/2 twisted shielded fire alarm cable add EMI protection, while unshielded versions remain cost-effective and flexible for general installations.

Conductors are stranded bare copper, providing a balance between durability and conductivity. Configurations such as 18/2 twisted pair unshielded fire alarm cable minimize signal loss across extended runs.

Key Features

The key features of the 18/2 fire alarm riser make it an optimal choice for residential and commercial usage. Here is what you can get from it.

Conductor and Insulation

The conductors use stranded 18 AWG bare copper with PVC insulation. These cables are rated up to 300V and can maintain stable transmission in demanding fire alarm circuits.

Shielding Variants

Options include 18/2 shielded fire alarm cable and foil-shielded twisted pairs. It is designed to minimize electromagnetic interference.

Jacket Ratings

• Riser-rated (CMR): Approved for vertical riser shafts.
• Plenum-rated (CMP): Choose 18/2 CMP fire alarm cable for air-handling spaces.

Cable Lengths

Standard reels range from 500 ft. to 1000 ft., suitable for residential, commercial, and industrial projects.

Applications

• Fire alarm control panel wiring
• Initiating device circuits (pull stations, detectors)
• Notification appliances (strobes, horns)
• Security, intercom, and signaling systems
• Access control wiring

Buying Guide

• Check rating: Riser for vertical, plenum for air ducts.
• Shielding needs: Use shielded for high-EMI zones.
• Length: Plan installation to avoid splicing.
• Stranded vs. solid: Stranded is flexible, and solid is more rigid.
• Copper quality: Always confirm true copper vs. CCA.

FAQs

What is 18/2 fire alarm cable used for?

It connects fire alarm panels to devices like detectors, strobes, and pull stations.

What’s the difference between riser and plenum fire alarm cable?

Riser is for vertical shafts; plenum is for return-air spaces with stricter flame and smoke safety.

Is an 18/2 shielded fire alarm cable necessary?

Yes, in areas with heavy EMI, such as HVAC rooms or near elevators.

What does twisted shielded 18/2 fire alarm cable do?

It reduces crosstalk and improves signal clarity, lowering the risk of false alarms.

Can 18/2 fire alarm cable be used outdoors?

Standard riser versions are indoor-only. Use direct burial or UV-rated jackets outdoors.
